SPECIFICATION forming part of Letters Patent 'No. 532,570, dated January 15, 1895.

Application led April 5, 1894. Serial No. 506,394. (No model.)

To all whom it may concern.-

Be it known that I, GUs'rAv LEUoHs, of Darmstadt, in the Grand `Duchy of Hesse and Germ-an Empire, have invented a new and liseful Steam-Generator, of which thefollowing is a specification, reference being had therein to the accompanying drawings.

The object of the present invention is the novel arrangement of transverse boilers especially on Water tube boilers havingat the same time the object of making the most of the fuel and toeffect a smokeless combustion of the same, and to promote a more sufficient circulation of the water.

The object of this invent-ion is represented in the annexed drawings.

Figure 1, represents a longitudinal section through the brickwork of the boiler plant and a view of the whole plant with two cross boilers added. Fig. 2,-isa cross section after the linesx, y, .e of Fig. 1. Fig. 3, is a longitudinal section through the brickwork and a view of the Whole plantwith one cross boiler. Fig. 4, is a cross section on the lines y', z of Fig. 3. Fig. 5, is a vertical section through the upper boiler showing a modification of the arrangement shown in Fig. 4.

The grate S is inclined in such a manner that the fuel consumed is replaced automatically .by fresh fuel, coming from the feeding space F placed at the upper end of the grate. Aperfectly smokeless combustion is produced by the sliding ofthe fuel over the grate, the same taking the place of that already consumed, in connection With the regulatable feeding of air by the channel O and bythe peculiar position of the cross boilers A and B whereby the Way of the smoke is determined, the same striking against the walls of the cross boilers, receiving a turning motion and is thus united with the hot lire gases. The best Way is to take transverse boilers, the one A replacing the fire bridge, the boiler B being placed above the fuel feeding space F. Both these transverse boilers are connected by large but short pipes E and D at the top and at the bottom. These transverse boilers are connected with the upper boiler O by the tube b serving for feeding the water, and for this purpose b goes from the water room ofthe upper boiler nearly to thebottom of the transverse boiler A. At the top ofthe transverse boiler B, op-

posite to the tube b is provided a tube a, of corresponding dimensions which goes almost to thesteam room of the upper boiler O', the tube or having hereby the object to lead the steam bubbles produced in both transverse boilers back to the steamv collector of the boiler. By this peculiar connection established between the two transverse boilers and between both and the upper boiler O double circulation is eifected in the Whole plant. The one circulating current begins at the upper boiler O', from whence the water passes, by way of the tube b, to the bottom of the crossboiler A through the pipe D to the transverse boiler B, and through said boiler to the opposite-end, the hot water and steam passing through the tubea into the upper boiler and v,

the cooler water through E into the cross boiler. A following the same course.

One part of the watecwhich enters the upper boiler O by the tubea joins the cooler Water in the .upper boiler and -flows with it through the tubeb into the transverse boiler A, beginning here, in part, the above mentioned circuit again into the pipe E into the cross boiler B and from here through tube a back into the upper boiler.

Because the circulating water passes always with a quick motion over the top and bottom of the transverse boiler all settling of mud therein becomes totally impossible and the steam power'need not be wasted removing the bubbles adhering to the inside cover of the boiler.

Both transverse boilers may be placed horizontally or in an inclined position and instead of being connected with the upper boiler they may beconnected with the Water space W, whose one Wall is made up by the tubes mentioned above.

If a plant of minor extension be employed the transverse boiler B may be omitted. In this case the tubes a and b are made larger for allowing the proper circulation and both a and b will be arranged in such a manner,

vthat sufficient circulation is effected and.

same smaller outside of the boiler A where tube a enters, and goes from here longitudinally inside across this boiler inishing inside near the bottom of the other smaller outside of the same which is opposite to the tirst men` tioned one, thernost" important feature of this construction being that the water feeding tube b issues at that side of the boiler which is opposite to that wherein the steam pipe enters.

In Fig. 5 a inode of execution is shown wherein the tubes a and Z2 issue from different sides of the upper boiler O2 and enter at different sides of the cross boiler A.

K is the masonry in the figures; R, the tube system carried by water room W'.

The most important currents of water are indicated by arrows.

I claim- 1. In a steam generator, the lire chamber, the upper boiler O', the inclined grate, the transverse boiler A acting as the iire bridge at the rear of the grate, th'e front transverse boiler B in a higher plane than the boiler A, the upper and lower inclined tubes D and E at different ends of the boilers, the pipe ct eX- tending from the upper part of the upper cross boiler to the boiler O and the pipe l) extending from the said boiler O to the lower part of the fire bridge boiler, whereby the circulation will be upward through the pipe D from.

the boiler A to the boiler B thence through the pipe a, boiler O and pipe b to the cross boiler A and also downward between the lower parts of the boilers through the pipe E, substan-I tially as described.

2. In a steam generator, the tire chamber, the upper boiler O', the inclined grate, the fire bridge cross boiler A, the cross boiler B in a higher plane, the pipe connections between the cross boilers and the pipe connections to the upper boiler O said boilers A, B, presenting a double iiaring opening for the passage of the products of combustion with curved walls whereby the said products are given a rolling motion to be eommingled with and ignited by the furnace gases, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
